This invention relates to improvements in pipes.

An object of this invention is to provide a pipe wherein the stem may be maintained in a free and open condition, thereby eliminating the need of frequent cleaning.

Another object of this invention is to provide a pipe wherein the smoking material such as tobacco may be entirely reduced to an ash in a dry condition for easy removal from the pipe bowl or receptacle.

A further object of this invention is to provide a pipe constructed in such a manner that the smoking material will be suitably confined within the container thereby eliminating the obiec tionable scattering of tobacco and ash particles.

Other objects of the invention will appear from the following detailed description of the device, and as disclosed in the single sheet of drawings herewith made a part of this application.

In the drawings,

Fig. 1 is a perspective view of the pipe.

Fig. 2 is a sectional view of the pipe.

Fig. 3' is a modification of the invention.

Fig. 4 is a further modification of the invention.

In the pipe according to this invention numeral 1 designates the bowl made of any suitable material, and provided with a projecting portion 2 having a bore 3 extending therethrough, and in open communication with the interior of the bowl 1. A mouth piece 4 is adapted to be detachably connected to the portion 2 in the usual manner.

The bowl 1 is provided with open ends adapted to be closed by means of caps 5 and 6, and has an upper air chamber 10, and a lower chamber '7 for receiving the smoking material, the bore 3 being in open communication with the air chamber 10. The chambers 7 and 10 within the bowl 1 are formed by means of a partition 11 made of any suitable material and provided with perforations l5. Openings 8 and 9 are formed in the bowl of the pipe and in communication with the smoking material '7 for giving proper draught when using the pipe.

The modification shown in Fig. 3 calls for a bowl 13 having an open end adapted to be closed by the cap 12, the perforated partition 14 separating the bowl 113 into upper and lower chambers 1'7 and 18, while the stem portion 16 extends in open communication with the upper or air chamber 17. Suitable openings 19 and 20 ex tending through the bowl 13 are provided for the tobacco receiving chamber 18.

In using it is preferred to load the pipe from the lower end by removing the cap 6, inserting the smoking material in the chamber to a proper compactness, and then closing the chamber 7 by means of the cap 6. The openings 8 and 9, of which any number may be formed, are located preferably in the lower periphery of the chamber 7, and are sufiiciently small to prevent the contents of the material chamber '7 from sitting through, and in such a manner that when the pipe is in use they will, in connection with the perforated partition 11, function to cause the smoking material to be reduced to a line and dry ash without the air passing through the ash and thereby impeding the draught, and permitting a positive easy removal of the ash from the material chamber, while the bowl and stem will be free from the usual gumming substance, and the pipe easily cleaned. Either opening 8 or 9 is to be fitted with a funnel shaped metal tube for lighting the pipe. This invention and pipe construction also assures a more continuous and uniform combustion so that the pipe may be smoked with comfort and slowly, and further assures a complete burning of the tobacco. It also appears to prevent irritation or biting of the tongue and tissue of the mouth. 7

After lighting and placing in condition for use, the pipe should be inverted in smoking. The closing of the open ends will eliminate the promiscuous scattering of loose tobacco and ash andsparks which is very obvious as an advantage.

Fig. 4 is a further modification of this invention, wherein the pipe is provided with a main body portion 21, and a partition 22, which should be made of a substantial metal for aiding radiation, and combustion when it becomes heated, and tightly inserted from the bottom against a shoulder 23 above which an upper air chamber 24 is provided into the top of which a pipe stem 26 is adapted to lead.

The pipe being loaded from the bottom, the pressure of the tobacco against the cross piece cannot dislocate it, for it is held against the shoulder. The hole 25 for the stem 26 should be arranged as near as possible to the top for removing it from contact with any glutinous matter or oils or other matter from the tobacco 27 which might choke the pipe stem. This arrangement assures a more complete process of combustion, and this form of the pipe has a lower smoking material receptacle 28 provided with open ends and detachable plugs or caps 29 and 30 for clos ing both ends.

The metal partition 22 is perforated with holes 31 sufficiently small to prevent the tobacco from falling into the upper air chamber 24 when the pipe is loaded, the perforations 31 being sufficient in number to permit the free passage of the smoke drawn from the lower receptacle and to prevent choking.

The pipe is preferably to be loaded from the bottom as stated above. The plug, or closing portion, at the bottom is to be inserted after the pipe is loaded with the tobacco, but it need not be closely pressed. The draft is upward so as to provide a more complete combustion, the tobacco not being wasted and the nicotine and glutinous matter more completely burned than in present devices.

Two suitable bottom openings are provided in the side of the pipe so as to be above, or nearly so, the ash, a small one 32 on the opposite side to the stem, very small for draft purposes, and another one 33 nearly opposite, but not exactly on the same plane, so that if there happens to be an obstruction on one plane, it may not be on both. The opening 33 is made large enough for lighting the pipe after the device is closed at the bottom by the plug or other closing element. The opening 33 is adapted to have inserted in it a small metal tube 34 of such dimensions that the ash will not pass through, nor ordinarily, the smoke. The tube 34 is arranged to extend a suitable distance, approximately to the center of the tobacco receptacle 28, for the purpose of carrying the flame from the match into the tobacco and lighting it in the middle, thereby starting the combustion better and more evenly.

The openings 32 and 33 are adapted to admit the air for the combustion. A metal cuff 35 is arranged at the outer end of the tube 34 for fitting outside around the opening 33 in order to prevent the lighting match fiame from burning the pipe.

When the pipe is drawn on, the flame from the match extends in through the tube 34. The tube 34 may be inserted in a hole through the bottom of the pipe if desired, and is made a little funnel shaped, the small end being inside the pipe chamber. This arrangement will take the flame better from the match, and more efiiciently project it into the tobacco. The tube 34 being metal, heats readily and carries the flame well. The pipe is smoked with the main part of the pipe hanging down, so that the combustion will be from the bottom instead of the top as in present pipes, and in this way, and on account of the other features, a more complete combustion of the material will take place in the lower receptacle 28. The stem 26 is left free and clear from the gummy substances and thereby prevents the pipe from becoming as strong as in the case of the pipes in common use. The stem 26 is placed near the top of the air chamber 24 better to prevent it being reached by any of the unconsumed glutinous matter, and become clogged as now often happens in pipes.

The plug at the top of the pipe 29 above the air chamber 24 is not intended to be removed, except when it may be desired to remove both plugs in order to run water through the pipe to clean or scrape it, or if clay or other noncombustible material, to burn the pipe out in fire in order to clean it.

This invention in a pipe construction assures a more continuous and uniform combustion, as stated above, so that the pipe may be smoked with comfort and slowly with a maximum burning of the tobacco and to avoid, to a greater degree, the biting and irritation of the tongue and tissues of the mouth and throat. The air chamber 24 may be of any desirable proportionate size to the rest of the pipe, and will function in part to cool the smoke.

The closing of the open ends will eliminate the scattering of tobacco, ash and sparks which is the obvious advantage and will prevent, to a degree, the smoke from getting into the eyes.

It may be pointed out that the cross piece or perforated metal portion should be substantial and positioned against the shoulder in a horizontal manner, and that the air chamber should preferably carry the pipe stem near the top and will operate to cool the smoke as well as prevent the gumming of the stem. In order that the perforated cross portion should remain permanent, the piece should be sprung in or inserted tightly, and as stated be of a thickness which will help the radiation and more completely aid in the combustion and cooling process, one great object being to prevent the gumming of the stem. The cross piece should be, preferably, of metal.

The air chamber need not be in one piece or of the same material as the pipe. The pipe may be of meerschaum, briar root, or other material. The air chamber may be made of metal inserted at the top of the pipe or otherwise, and retained there in some suitable manner, in which event there need be no plug in the top, the metal air chamber being preferably a cup afiixed upside down and removable for the purposes as stated above. In a metal air chamber the radiation would be more complete and the smoke better cooled. There would be no occasion to touch the upper air chamber, if of metal, and heated, for the pipe could be held by the fingers from below.

The bottom plug, if a plug be used, must be fairly tight to hold the tobacco during the combustion, but the bottom may be hinged with a catch or screwed on.

The pipe stern and draught through it should not be inside of the air chamber, or bent up through it, because the smoke will become better cooled if drawn from the air chamber, and because the construction according to this invention is simple and less expensive to manufacture, and because it will be less apt to clog or gum up.

The pipe may be of different sizes and shapes, and ornamented or carved in any desirable way. The air chamber and tobacco receptacle may be properly proportioned to suit conditions. It is desirable to have at least one flat end, preferably at the top, so that the pipe may be laid down on that end, although this is not essential to the invention. The ends when closed may be of any ornamentation or shape. The pipe may be so constructed that it can be laid down fiat, or on one or either end.

What I claim is:

1. In a pipe having an upper air chamber, and a stem leading thereto, a lower smoking material chamber in open communication with the upper air chamber, a perforated partition arranged therebetween, an igniting, opening leading into the lower chamber, and a hollow shaped element extending through the igniting opening and into the central portion of the smoking material chamher.

2. In a pipe having an upper air chamber, and a stem leading thereto, a lower smoking material chamber in open communication with the upper air chamber, a perforated partition arranged therebetween, an igniting opening leading into the lower chamber, and a hollow shaped element extending through the igniting opening and into the central portion of the smoking material chamber, the hollow shaped element being provided With an extending flange for protecting the pipe.
